Re: posi rear

posi is not real common but the 12 bolt is fairly common.

Re: posi rear

I was under the impression that all these trucks came with 3.73 from all the guys I have talked to around here. LOL I think most I have ever driven were 3.08s....I know mine is.I know basically which trannies had which ratios as standard equipment,it was just funny how many people that say they have 3.73 or 4.10s and have never had the covers off.
